Of a sample of 36 cattle from Alberta, Canada, (examined from June to September, 1986) 9 (25%) were found to be infected with T. skrjabini. A total of 77 worms were recovered, mainly from the lacrimal glands, but a few were found on the surface of the eye. From 1 to 41 parasites were isolated from...

Abstract

The efficacy of ivermectin at a dose rate of 200 µg/kg bodyweight given on days 29 and 64 after turnout on pasture was determined on the basis of faecal egg counts and growth rates in 99 yearling beef cattle with naturally acquired nematode infections. Non-medicated control cattle (104 animals)...

Abstract

Yearling steers all excreting low numbers of strongyle eggs and weighing 282-430 kg were randomly allocated into 2 groups of 50 steers each. The treatment group were given ivermectin (200 µg/kg body weight) on 2 occasions (day 0 and day 60). Both groups were grazed on a permanent pasture. Egg...

Abstract

The distribution of T. skrjabini in the eyes of 297 cattle in Alberta, Canada, was examined from necropsies on 297 animals. Although the overall prevalence in 227 beef cattle (21.5%) was similar to that in 70 dairy cattle (25.7%), in general, worms were more abundant in beef than in dairy animals....

Abstract

Two herds of cows and their calves which were kept on separate but similar pastures were used in the study. The treated group consisted of 44 cows and 44 calves; the untreated control group consisted of 45 cows and 45 calves. Calves were given ivermectin (200 mg/kg s.c.) on June 29 (when calves...

Abstract

The anthelmintic efficacy of ivermectin (administered subcutaneously at 200 µg/kg bwt) was assessed for control of T. skrjabini in experimentally infected calves. 24 uninfected male Holstein calves, 1-2 weeks old, were artificially infected with Thelazia skrjabini by placing 15 3rd-stage larvae...

Abstract

The eyes from 410 beef cattle grazing 6 range pasture zones in Alberta, Canada, were dissected and examined for species of Thelazia. 38 (9.3%) contained eyeworms: 25 (6.1%) contained T. skrjabini alone, 3 (0.7%) contained T. gulosa alone, and 10 (2.4%) had a mixed infection of T. skrjabini and T....

Abstract

The anthelmintic efficacy of doramectin was assessed for the control of Thelazia spp. in 2 studies using 44 naturally or experimentally infected calves. Cattle were randomly assigned based on weight to either a doramectin treatment group or a saline control group. Treated animals received...

Abstract

Trihedron sticky traps were used to monitor the prevalence and intensity of Thelazia spp. in face flies associated with 2 groups of cattle. Traps were set for 24 h once a week beginning 2 weeks before cattle were turned out to pasture following winter housing and continued until flies reached...
